Upon arrival, I found the evaporator coil frozen. I returned to check the system pressures and verify proper operation. I turned the system on in cooling mode and monitored its performance. The system was operating and cooling properly at the time of inspection. The following readings were recorded: * Suction pressure: 120 PSI * Liquid pressure: 309.5 PSI * Superheat: 15°F * Subcooling: 11°F * Return air temperature: 75.7°F * Supply air temperature: 57°F * Temperature split: 18.7°F Based on these readings, the system is currently cooling within an acceptable range. Additional Findings and Recommendations: There is a high possibility that the previously identified maintenance and repair issues are contributing to the evaporator coil freezing up. The following work is recommended: 1. Remove the evaporator coil for a thorough cleaning. 2. Clean the blower wheel, which is heavily affected by debris. 3. Replace the pitted contactor. 4. Replace the capacitor. 5. Perform microbial sanit

Performed a diagnostic on a 4-year-old Goodman 3-ton straight-cool system with electric heat. I checked system operation in both cooling and heating modes. The system is currently operating in both modes. I checked compressor amperage, condenser fan motor amperage, blower motor amperage, electric heater amperage, refrigerant pressures, subcooling, superheat, and temperature split. During the inspection, I found the following issues: * Condenser coil is dirty. * Contactor is pitted. * Evaporator coil is dirty. * Debris buildup on the blower wheel. * Bacterial growth present on the evaporator coil and inside the air handler cabinet. * Drain pan is dirty. * Supply plenum has air leakage. Although the system is currently operational, it is not operating efficiently and is outside manufacturer specifications at this time. I prepared an estimate for the recommended repairs and cleaning services and presented it to the customer. The customer decided to keep the system as it is for now due

Performed a leak search on the newly installed Daikin system and found a refrigerant leak at the factory brazed connection on the liquid line. I documented the leak with a video showing bubbles during the leak detection process. I repaired the leaking connection by re-brazing it while flowing nitrogen through the line to prevent oxidation. After completing the repair, I pressure-tested the system and performed a vacuum, pulling down to 375 microns. I then released the refrigerant and added 6 pounds of R-32 refrigerant. After completing the repair and charging the system, I checked its operation. The unit is cooling and draining properly at this time.

Performed a diagnostic on the downstairs Goodman unit, approximately 9 years old. Found the system drain line clogged, causing the safety float switch to fill with water and interrupt the thermostat voltage as a safety precaution. Contacted Paul and received approval to perform the drain cleaning. Cleared the drain line and flushed it with approximately 6 gallons of hot water until the water ran clear. Cleaned the drain pan and applied Viper treatment. After completing the drain cleaning, I tested the system operation and confirmed the unit returned to cooling mode. I also inspected the electrical components. The capacitor was within manufacturer specifications; however, the condenser contactor was badly pitted. Contacted Paul again and received approval for contactor replacement. Replaced the contactor and tested the system again. The system is cooling and draining properly, and all components are operating normally at this time.

Performed a diagnostic due to the drain line overflowing and activating the safety float switch. The customer showed me water trapped inside the return duct. The system also has another drain trap installed underneath the slab with a vent pipe. The customer reported attempting to clear the drain line multiple times, but the issue continued. I ran a drain snake through the line from outside to inside and from inside to outside. I found debris and significant algae buildup inside the drain line. When testing drainage directly from the drain pan, I noticed that the water was still overflowing. I then cut the drain line near the drain pan and identified a blockage. I cleared the blockage, cleaned the drain line, and reconnected the piping using PVC glue. I flushed approximately three gallons of hot water through the drain line until the water ran clear. A significant amount of algae and debris was removed. I also cleaned the drain pan and applied Viper drain treatment. After completing

Recovered the refrigerant from the condensing coil. Flowed nitrogen through the refrigerant lines during the installation process. Installed a new Teflon gasket and completed brazing with nitrogen flowing through the lines to prevent oxidation. Performed a pressure test at 350 PSI to verify system integrity. Once the pressure test was completed, evacuated the system to 360 microns. Released the refrigerant back into the system and added 5 pounds of R-410A. Started and tested the system operation. The unit is cooling properly and the condensate drain is draining properly at this time.

Performed preventive maintenance on the pool heater heat pump. Checked system operating pressures, contactor, capacitor, and temperature split between the pool water and evaporator coil. Verified that the capacitor is operating within the manufacturer’s specifications. Inspected and rinsed the condenser coil to remove accumulated debris. Tested overall system operation and confirmed that the pool heater is operating properly at this time.

Performed preventive maintenance under the maintenance contract on the gas furnace. Tested system operation in heating mode and found the furnace operating properly. However, I noticed the unit is equipped with a two-stage gas furnace, but only the low stage is currently connected and operating. The W2 wire is not connected, preventing the furnace from operating in high-stage heating and reaching its full heating capacity. I brought this issue to the customer’s attention and explained the importance of connecting the W2 wiring and programming the thermostat for two-stage operation. I offered to have the wiring connected and the thermostat properly programmed, but the customer declined the recommendation at this time. I also tested the system in cooling mode and confirmed proper operation. Checked compressor amperage, condenser fan motor amperage, and indoor blower motor amperage. Capacitor readings are within manufacturer specifications, and the contactor is in good condition. Addit

Performed a system diagnostic and found the condensate drain line extremely clogged. I cleared the blockage by running a drain snake from inside to outside and outside to inside. I then applied Drain Solve and allowed it to sit for 15 minutes to break down the buildup. Afterward, I flushed the drain line until the water ran clear. The drain pan was clean; I brushed it and applied Viper drain treatment. I also flushed the drain line with approximately 6–8 gallons of hot water. Finally, I tested the condensate drainage and confirmed proper water flow. The system is draining properly and cooling at this time.

Performed a diagnostic on a 23-year-old Thermo-Start heat pump system. The unit was calling for cooling but operating in heating mode. I checked the reversing valve wiring from the thermostat to the outdoor unit and confirmed that the reversing valve signal was energized. However, when checking the output from the defrost control board to the reversing valve solenoid, I measured only 3.2 volts instead of the required 24 volts. While inspecting and manipulating the board terminals, I noticed that the system switched back to cooling mode. This indicates an intermittent issue with the defrost control board, potentially caused by a loose terminal, damaged terminal connection or mounting support, or a faulty board relay. The control board is not field-repairable, and replacement of the defrost control board is required to address the issue. I explained to the homeowner that the replacement board may still be available but would likely need to be special-ordered due to the age of the equi
